rig truck help

[welder_one]

got the bed completely tore off about three days ago, and went and picked up steel to make another flatbed frame for it.

[welder_one]

i used this stuff called metalize. its a rust converter and changes rust into a primered surface that can be painted. i used it on steel structures around swimming pools before. neat stuff. i laid out the frame for the flatbed last night and welded it together. i used 1 1/2 x 1 1/2 square tube 3/16 wall for the frame runners that follow the truck frame. the rest is 1 1/2 square tubing 11 guage, except for the sides. there, i used 2x2 1/4 angle. i did that so that i can use tie downs and straps easily. the last one is hard to see. it was late. i used .080 aluminum plate to mount the lights.

this morning , i picked up some lumber and carriage bolts. they are 2x6. the bolts i used are 4 inch 316 stainless at 5/16 diameter.







I HATE DRILLING HOLES!!!!!!!!!!!!!!



lol.........100 bolts to be exact.

i built a headache rack for it today and pulled new wires for the brake lights. i will post pics of the rack later.


does anyone know anything about quadrajunks? the truck has a bad stutter when under full throttle. any other throttle position, it does real well. i dont know enough about them to try and adjust it, also the secondaries arent opening (probably the stutter) and i cant figure out how to get them freed up. they will open by hand but not by throttle linkage

[Black Wolf]

If you have a Rochester Quadra Jet w/ vacuum secondaries, it NOT going to open with the throttle linkage. If it stumbles or bogs as soon as you floor it, your accelerator pump may not be functioning properly. It may have nothing to do with the secondaries, but a momentary lean condition until the main fuel bleed circuit catches up. Time to pull the top off, clean it up & maybe throw in a rebuild kit while you're at it.

Sorry to suggest more work.

work is something that i am not afraid of, especially more of it. i have never been into a rochester, black wolf, may i pm you if i have more ?'s about it

[welder_one]

here are pics of the headache rack

[fun4now]

looks more like a backack rack to me. you head is still above it.

[Black Wolf]

By all means PM away. No need to ask but the gesture of respect is appreciated. Always glad to help out.

Carb advice

The best advice I could give you on the Quadrajet is take it off and put yourself on a Holley 4412 and an adapter plate. Qj's are good if you get them dialed in right but a real nightmare if you don't know much about them. The Holley 4412 on the other hand is a great 500 c.f.m. 2bbl. carburetor, it'll save you some money on gas and is very simple to repair if needed. Dave

The last 351W street engine I built, ended up with and Edelbrock Performer on it. Fashioned much the same as the Rochester, but with a few upgrades and a nice shiny finish. Metering rods were easy to change. Metering jets weren't much more work, as the carb came apart nicely, and didn't damage the gaskets.

Did a fair amount of work too with the Holley 4180C that came factory on the mid 80's Ford small blocks. Vacuum secondaries etc. At any given time I had 6 or 7 complete carb kits in a drawer in my toolbox, power valves, vacuum springs, etc. etc. Oh, to have the good old days back again.

Carburetor??? Whats that?? it has been along time but used to put kits in Q-jets all the time. I liked them OK, Last one I worked on was in a boat about 15 yrs ago. I think Blackwolf is correct in his thoughts on your carb problems, however dont forget all the simple and often overlooked items. Maybe you have already checked this stuff but Ignition system issues can also cause stumbling. Although I'm sure if its been sitting up it needs a kit in the carb. Or for that matter all tune up parts. I guess those were the good old days but I have to say if I had a choice I'd pick fuel injection over a carb, so I guess these days are good too. Just requires more tools more $$ Good luck and keep up with the pics I enjoy following the progress.

well, i dug a little deeper this afternoon, and found that when you push the linkage into w.o.t. it squirts a fine stream of fuel all over the intake. i am going to try and find an edelbrock performer for it. not that i am afraid of the q-jet, just not much time.i already have a dual, high rise weiand intake that will fit nicely onto it so that the edelbrock will bolt right up. i have used the performer carbs many times in the past and like its reliability.

i rebuillt the distributor, whether it needed it or not. new weights and springs, pick-up coil, coil, and cap and rotor. plugs and plug wires as well. i missed toying with the hei ignition. its been a little while for me. my first truck was a 79 3+3 dually 4wd. (it was cheap, and i learned about a small block quickly)

[fun4now]

i rebuilt the distributor, whether it needed it or not
thats the best way to go if its to be a work truck. you don't want to miss out on or hold up a $1,000.oo + day over some thing small you didn't do when getting the truck ready. its time and $$ well invested to do it right now, before its loaded and got some where to be.
sounds like its coming along nicely.

Good thing about the old engines, everything is cheap for them and still avaliable. I would have done the same thing with the ignition, probably not been changed in along time and moisture and age tells on ignition components.
I dont understand what you mean by squirting a fine stream all over the intake?? Engine not running, Work linkage by hand, accelerator pump will squirt fuel into intake. Sorry for the questions, just didn't want you to spend more than you need to Good luck, looks like your making good progress
